I have not put down my arms yet

Narrated Al-Bara:

A man whose face was covered with an iron mask (i.e. clad in armor) came to the Prophet and said, "O Allah's Apostle! Shall I fight or embrace Islam first? "The Prophet said, "Embrace Islam first and then fight." So he embraced Islam, and was martyred. Allah's Apostle said, A Little work, but a great reward. "(He did very little (after embracing Islam), but he will be rewarded in abundance)."

Narrated 'Aisha:

When Allah's Apostle returned on the day (of the battle) of Al-Khandaq (i.e. Trench), he put down his arms and took a bath. Then Gabriel whose head was covered with dust, came to him saying, "You have put down your arms! By Allah, I have not put down my arms yet." Allah's Apostle said, "Where (to go now)?" Gabriel said, "This way," pointing towards the tribe of Bani Quraiza. So Allah's Apostle went out towards them .
